Question

The estimate of
7789 - 539​

Answer 1

Step-by-step explanation:

⇒ The given two numbers are 5679 and 422.

⇒ In number 5679, its tens digit is 7, which is greater than 5.

⇒ So, we increase the digits at hundreds place by 1 and replace each one of the digits at tens and ones place by 0 to round off the given number to its greatest place.

∴ Round off 5679 to its greatest place is 5700

⇒ In number 422, its Itens digit is 2, which is less than 5.

⇒ So, we replace each of the tens and ones digits by 0 and keep the other digits as they are to round off the given number to its greatest.

∴ Round off 422 to its greatest place is 400

∴ Required number = 5700−400=5300

Answer 2

Answer:

The estimate of 7789 - 539 is 7300.

Step-by-step explanation:

In Mathematics, while numbers are subtracted, the end result acquired is known as a distinction.

• While subtracting the numbers, viable techniques are used.
• One is to get the real distinction and the opposite is the expected distinction.
• If the precise distinction is acquired, then it's miles known as the real distinction.
• The expected distinction method the distinction is acquired from the rounding off the given numbers.

But on this method, the precise variety isn't always acquired.

The numbers are =

• 7789 , it's tens digit is 8 , which is greater than 5 hence we will round it off to hundreds place by and ones place will have 0 .and it will become 7800
• 539, it's tens place is 3, hence it's less than 5. Therefore it will round off to 500.

The difference of =

$7800-500= 7300$

The estimate of 7789 - 539 is 7300.
